Using DBK Cards and Modules for Signal Conditioning
The DBK signal-conditioning cards and modules are designed for use with DaqBooks, LogBooks, and
various types of data acquisition boards, i.e., ISA, PCI, and compact-PCI types. The DBKs perform best
when used with an acquisition device that can dynamically select channel, gain, and range. DBK cards and
modules with dynamic channel and gain/range selection allow for high channel-to-channel scan rates with
a variety of transducers.
Note : Only passive DBKs, such as the DBK1 BNC module, the DBK11A screw terminal card, and the
DBK40 BNC analog interface, can be used with Daq PC-Cards.
DBK output signals can be bipolar, e.g., -5 to +5 V, or unipolar, e.g., 0 to 10 V. The user can select a
range of relevant values to correspond to the lowest signal (e.g., -5 or 0 V) and the highest signal (e.g., 5 or
10 V) signal. This type of range selection guarantees the highest resolution in 12-bit or 16-bit conversion.
DBK modules share the same footprint as the DaqBook and a typical notebook PCs; allowing for
convenient stacking. The majority of these modules have their own power supply; however, several
options exist for packaging and powering the DBKs.
Reference Note :
DBK options are detailed in the DBK Option Cards and Modules User’s Manual
(p/n 457-0905). As a part of product support, this manual is automatically loaded onto your
hard drive during software installation. The default location is the Programs directory, which
can be accessed through the Windows Desktop.
